POLE OR POST.

Application filed December 31, 1925. Serial No. 78,582.

invention relates to poles or posts for use particularly for supportingelectric transn'iission lines, as street lighting poles, as trolleypoles, as radio aerial masts, and the like` rIhe object of the inventionis to provide an open steel pole, that is, a pole of skeleton steelconstruction, without recourse to riveting, welding or bolting in theassembling of its component parts, thus providing a pole ot greatrigidity and strength, particularly in the connection oit its structuralmembers, and of relatively low manufacturing cost.

The invention consists, essentially, in a pole or post, or the like,comprising a plurality of longitudinal members having chalineled faces,lips flanking said channels, and a plurality of transverse members inthe 'form of diaphragme or spiders arranged between the longitudinalmembers at spaced intervals throughout their length, and provided witharms for engagement with the channels of the longitudinal members, thesearms being provided with knobs arranged for engagement with the lips ofthe longitudinal members, and these lips adapted to vbe clinched uponthe arms and the knobs thereby imbedded in the lips, to form a rigidconnection between the longitudinal members and the transverse members,as I will proceed now to explain and finally claim.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designa-ted, Figure l is anelevation showing a complete pole embodying my invention. Fig. 2 is anenlarged fragmentary detail of same. Fig. 3 is a section taken on theline 3-3 of Fig. 2. Fig. 4 is a plan view of a modiiied form oftransverse member of spider by means of which siX longitudinal membersmay be used in the construction ot the pole or post as distinguishedfrom the four longitudinal members illustrated in Figs. l to 3. Fig. 5is a side elevation ot the transverse member illustrated in Fig. 4i.Fig. 6 is a plan view of a further modiiication of the transversemember. Fig. 7 is a. side elevation ofk the form of transverse' memberillustrated in Fig. 6 and showing a longitudinal member connectedtherewith.

In the form of the invention illustrated in Figs. l, 2 and 3, I'haveshown a pole or post having four longitudinal members l, channeled asindicated at 2, these channels being formed and flanked by lips 3. Theselongitudinal members are arranged around transverse members or spiders4, spaced at suitable intervals throughout the length of thelongitudinal members, and having arms 5 provided with knobs 6 adapted tobe positioned within the channels of the longitudinal members and thelips 3 clinched upon them so that the'knobs are imbedded in the materialof the lips to form a rigid, nonslipping connection between thelongitudinal members andthe transverse members. By thus connecting theseveral longitudinal members by means ot the transverse inembcrs ordiaphragms or spiders, whereby no slippage or movement between the partsis permitted, I am enabled to produce an eX- cep'tionally sturdy andrigid pole construction.

As shown particularly in Fig. l, the pole may be gradually tapered fromtop to bottomv byl providing appropriate bends 7 in the longitudinalmembers, the transverse members or spiders being made of diminishingsize to accommodate the tapering of the po e.

In the form of the invention shown in Fivspl, 2 and 3, wherein only fourlongitudinal members are used, I prefer to form the transverse membersof two pieces of prei formed stock, provided, during their fabrication,with the rows of knobs 6, as shown, and these pieces I bend intosubstantial U- shape, as shown in Fig. l, to form the arms 5, and then Iplace one upon the other and weld the two together where they cross at8.

In Fig. 3 I have shown a section through one of the arms 5 and thelongitudinal member connected therewith illustrating the manner in whichthe knobs 6 are imbedded in the lips 3 when the latter are clinched uponthe arms 5.

When it is desired to construct a pole or post requiring morelongitudinal members than the pole of the type shown in Figs. l to 3, Imay use for my transverse members or diaphragms the arrangement ofpartsl shown in Figs. 4 and 5.

In this form of transverse member, I take a plurality of pieces 9 of theknobbed stock and bend them to angle form, as shown in Fig. 5, and thenI weld the ends l0 of these angles to a plate l1 which may be either ofcircular form, as illustrated in full lines in Fig. 4, or of angularl:`orm,'as illustrated in broken lines in Fig. l. The appropriate numberof longitudinal members to correspend with the number of members 9 maythen be assembled to form a post by clinching the lips of thelongitudinal members upon the knobs 6 of the portions l2 of the angles9.

In Figs. 6 and 7, l have illustrated a cast or forged transverse memberor spider having spacers 13 carrying at their ends arms 14; providedwith knobs l5. The longitudinal members are assembled upon spiders ordiaphragms ot this type in the same manner as hereinabove described byclinching the lips 3 upon the arms 14C and their knobs l5.

t By constructing a pole or post in accordance with my invention,whereby welding, riveting and bolting are dispensed with in theconnection of the longitudinal members with the transverse members, I amnot only e enabled to produce a pole or post at a lesser manufacturingcost than where welding, riveting and bolting are used, but the drillingof holes to receive rivets or bolts, and the weakening of the componentmembers of the pole caused thereby is done away with. Moreover, themanufacture of poles in accordance with my invention is much simpler andspeedier than by any other method with which I am familiar.

l have hereinabove described my invention as particularly adapted to theproduction of poles or posts tor use as supports ttor electrictransmission lines, as street lighting poles, .as trolley poles, asradio aerial masts and the like, but it is to be understood that it isadapted also to the production of structural columns for building`construction, or of reinforcing elements for use in concreteconstruction.

Various changes are contemplated as within the spirit of the inventionand the scope of the following claims.

l. A pole or post, or the like, comprising a plurality of channeledlongitudinal members having lips flanking their channels, and transversemembers having arms for cooperation with the longitudinal members, saidarms adapted to be positioned within said channels and provided withknobs for engagement with said lips, and said lips adapted to beclinchedV upon said arms, said clinching imbedding said knobs in saidlips to form a rigid connection between the longitudinal and transversemembers.

2. ln a pole or post, or the like, a plurality or' longitudinal members,a plurality or transverse members arranged at suitable spaced intervalsthroughout the length of the longitudinal members, and means forconnecting the longitudinal and transverse members comprising arms onthe transverse members and lips on the longitudinal members, the arms otthe transverse members being provided with knobs and the lips of thelongitudinal members being clinched upon the knobs or said arms, theknobs being thereby immovably imbedded in saidv lips.y

in testimony whereof I have hereunto set my hand this 29th day ofDecember, A. D. 1925.
